如何用vb得到网页的源代码
1 先加载网页:
Private Sub Form_Load()
WebBrowser1.Navigate "/question/.html"
End Sub
2 加载完成后取字符串到文本框:
Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Dim doc As Object, objhtml As Object
Dim strhtml As String
On Error GoTo errorsub
Me.Caption = WebBrowser1.LocationName & " 加载完成"
If MaxWebNum <= 0 Then
Set doc = WebBrowser1.Document
Set objhtml = doc.body.createtextrange()
If Not IsNull(objhtml) Then
strhtml = WebBrowser1.Document.body.innertext
Text1.Text = strhtml
End If
End If
Exit Sub
errorsub:
Text1.Text = "错误!!源码爬虫源码java!源码报价源码后台密码"
End Sub
VB如何获取webbrowser源码指定文本
先引用正则库,源码咸鱼源码怎么发货然后编写如下代码,源码药店进销php源码其中html的源码图形主力指标源码值替换为你问题中的html源码。Private Sub Form_Load()
Dim html As String
html = "<li><em>经验值</em></li><li><em>金币数</em></li>"
ExpeValue = FindFirstGroup("<em>经验值</em>(\d+)</li>",源码 html)
CoinValue = FindFirstGroup("<em>金币数</em>(\d+)</li>", html)
MsgBox "经验值为" & ExpeValue
MsgBox "金币值为" & CoinValue
End Sub
Private Function FindFirstGroup(pattern As String, src As String) As String
Dim re As RegExp
Set re = New RegExp
With re
.pattern = pattern
Set Matches = .Execute(src)
If Matches.Count = 0 Then
FindFirstGroup = ""
Else
FindFirstGroup = Matches(0).SubMatches(0)
End If
End With
End Function
